Doors of Perception (Doors) began life in 1993 as an international design conference, in Amsterdam. Since then, Doors has brought together grassroots innovators, entrepreneurs, educators, and designers to imagine alternative futures - sustainable ones - and take design steps to realize them. From 1993-2000, the conference was a project of the Netherlands Design Institute, a government-funded think tank. In 2000, Doors of Perception bv was founded - a small private company. Doors now acts a bit like a film producer: We conceive and organize projects, for the most part at a city-region scale, in which multiple partners use a variety of techniques to explore a meaningful question and design practical responses.
